Description
CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of Provisional Application Ser. No. 60/630,722, filed Nov. 24, 2004, the disclosure of which is incorporated by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to recreational vehicles with slide out rooms and, more particularly, to the trim assemblies and sealing members used with such slide out rooms.

2. Description of the Related Art

To permit their transport over the public highway system, recreational vehicles and other forms of mobile living quarters have a limited width. When such vehicles are parked, however, their width is no longer limited and it becomes desirable to enlarge the useable space within the vehicle. As a result, it has become common to equip such vehicles with “slide-out” rooms that can be withdrawn into the vehicle during transport over the public highway system and extended to provide additional living space when the vehicle is stationary.

The use of such a slide-out room requires an opening in a wall of the vehicle in which the slide-out room is located. The joint between the slide-out room and the vehicle wall must be adequately sealed to prevent the entry of water and small debris into the interior of the vehicle. Slide-out room openings have been provided with a variety of sealing members to prevent the ingress of water and debris. These sealing members generally perform adequately immediately following their installation but are subject to loosening and, over time, will oftentimes separate from the surface on which they are attached and fail to provide an adequate seal.

An improved structure that provides a long-lived and rugged sealing assembly for a slide-out room is desirable.

SUMMARY OF THE INVENTION

The present invention provides trim and seal assemblies that can be used with the slide-out room of a recreational vehicle and other similar mobile living quarters. The trim and seal assemblies of the present invention provide a rugged and reliable method for sealing the opening between the mobile structure and slide-out room and can be efficiently installed.

DETAILED DESCRIPTION OF THE INVENTION

A mobile structure 20 in accordance with the present invention is shown in FIGS. 1 and 2. In the illustrated embodiment, the mobile structure 20 is a recreational vehicle having an internal combustion engine 22 and wheels 24 whereby vehicle 20 is self-powered and can be driven over the public roadway system. As also seen in FIGS. 1 and 2, vehicle 20 has an exterior wall 26 with an opening 28 in which an enclosure 30 is located. Enclosure 30 is a slide-out room and is moveable between the retracted position shown in FIG. 1 and the extended position shown in FIG. 2. When slide-out room 30 is retracted into vehicle 20 in the position shown in FIG. 1, vehicle 20 has a width that permits it to be driven over the public roadway system. When vehicle 20 is parked, slide-out room 30 can be extended into the position shown in FIG. 2 to increase the usable interior space within vehicle 20.

Enclosure 30 is defined by four perimeter panels 32 and an exterior panel 34. Perimeter panels 32 include a floor panel, two sidewall panels and a roof panel. Exterior panel 34 closes off one end of panels 32. The opposite, interior end 36 of panels 32 is open to the interior of vehicle 20 and includes an outwardly extending flange 38 along its perimeter. Enclosure 30 has a construction similar to that of a conventional slide-out room. Panel 34 has a plywood substrate with aluminum sheeting on its exterior surface. Similarly, panels 32 have plywood substrates with aluminum or polymeric sheeting on their exterior surfaces. The interior of panels 32, 34 may be covered with a fabric or other material suitable for the interior of a recreational vehicle.

Exterior wall 26 of vehicle 20 has a first major surface 40 that faces the interior of vehicle 20 and an opposite second major surface 42 that forms an exterior surface of vehicle 20. An edge surface 44 (FIGS. 5 and 6) extends between interior and exterior surfaces 40, 42 and defines opening 28 in which enclosure 30 is located. The relationship of wall 26 with enclosure 30 is shown in FIGS. 3 and 4 which provide a cross sectional view of one of the side perimeter panels 32 and the trim assemblies secured to wall 26 at opening 28. Cross sections through the upper (or roof) perimeter panel 32 and lower (or floor) perimeter panel 32 would be substantially similar to the cross sections shown in FIGS. 3 and 4 whereby the trim assemblies shown in FIGS. 3 and 4 substantially circumscribe the entirety of rectilinear opening 28.

As seen in FIG. 3, and in greater detail in FIG. 5, when enclosure 30 is in its retracted position located substantially within vehicle 20, an outer flange 46 located on enclosure 30 and formed of an aluminum extrusion is positioned near exterior surface 42. Outer flange 46 has a seal member 48 mounted thereon to engage trim member 50 and thereby seal opening 28 when enclosure 30 is retracted.

Trim member 50 includes has an L-shaped base portion 52 with a first leg 54 and a second leg 56. Trim member 50 also includes a flexible member 58 extending outwardly from second leg 56. As can be seen in FIG. 8, base portion 52 of exterior trim member 50 has an L-shaped metallic substrate 60 that has a polymeric coating 62 with flexible member 58 being integrally formed with polymeric coating 62. In the illustrated embodiment, substrate 60 is a roll-formed aluminum. After forming substrate 60, coating 62 and flexible member 58 are coextruded over substrate 60 to form exterior trim member 50. Coating 62 is a 20% talc filled polypropylene and flexible member 58 is a thermoplastic olefin or thermoplastic elastomer. Alternative materials may also be employed with the present invention.

As best seen in FIGS. 3-6, flexible member 58 extends outwardly with its distal free end being deflected by and engaging an adjacent panel 32. Flexible member 58 thereby functions as a wiper, removing moisture and small debris from the engaged panel 32 when enclosure 30 is moved between the positions shown in FIGS. 3 and 4. This is most valuable when enclosure 30 has been in an extended position for a period of time, for example, vehicle 20 may remain parked for several days, and the exterior surface of panels 32 have been exposed to the external environment. In such a situation moisture and debris, such as dew and leaf clutter, may collect on panels 32. As enclosure 30 is retracted to enable the transport of vehicle 20, wiper 58 will remove a significant quantity, if not all, of the moisture and debris on panels 32.

Another trim member 64 is located on the opposite side of opening 28. Interior trim member 64 includes a substantially L-shaped base portion 66 having first and second legs 68, 70 and a seal member 72 integrally formed on first leg 68. Trim member 64 is a coextrusion with base portion 66 being a semi-rigid thermoplastic elastomer and bulb compression seal member 72 being a less rigid thermoplastic elastomer. For example, base portion 66 may be formed with Sarlink 4190 commercially available from Koninklijke DSM N.V. of the Netherlands and seal member 72 may be formed with C-Flex® 35 commercially available from Consolidated Polymer Technologies, Inc. of Clearwater, Fla. Other suitable materials may also be employed to form trim member 64.

FIG. 7 illustrates interior trim member 64 prior to its installation on wall 26. As shown, legs 68, 70 of trim member 64 define an acute angle 74 prior to installation. This configuration allows trim member 64 to be secured to wall 26 solely with mechanical fasteners extending through second leg 70. To install trim member 64, it is fitted to the right angle corner formed by interior surface 40 and edge surface 44. When second leg 70 is secured to wall 26 by driving a mechanical fastener 76 through second leg 70 and edge surface 44, first leg 68 is firmly biased against interior surface 40 because its engagement with interior surface 40 has biased legs 68, 70 into a configuration forming a substantially 90 degree angle.

As shown in FIGS. 3-6, first leg 68 of installed trim member 64 overlays interior surface 40 while second leg 70 overlays edge surface 44. A T-shaped aluminum extrusion 82 is located at the joint between panels 32 and interior flange 38 on enclosure 30 and forms that portion of interior flange 38 which is positioned adjacent to interior surface 40 when enclosure 30 is in its extended position. As best seen in FIGS. 4 and 6, seal member 72 located on first leg 68 is positioned adjacent opening 28 and engages T-shaped aluminum extrusion 82 to seal opening 28 when enclosure is in the extended position.

Exterior trim member 50 is fitted to the right angle corner formed by exterior surface 42 and edge surface 44 with two sets of mechanical fasteners. First leg 54 of trim member 50 overlays exterior surface 42 and fasteners 78 are extended through first leg 54 and exterior surface 42 to anchor leg 54 to wall 26. Second leg 56 of trim member 50 is located within opening 28 and overlays edge surface 44. As best seen in FIGS. 5 and 6, a portion of the distal ends of second legs 70, 56 of trim members 64, 50 overlay one another and define an overlapped region 80. Fasteners 76 extend through these overlapped portions 80 to thereby simultaneously secure both trim members 50 and 64.

In the illustrated embodiment, trim member 50 has spaced apart openings (not shown) that are preformed in legs 54 and 56 to facilitate attachment with fasteners 76, 78. Trim member 64, however, does not include such preformed holes and fasteners 76 are driving through leg 70 during the installation process. Fasteners 76, 78 are threaded fasteners in the illustrated embodiment, however, nails, staples and other suitable fastening means may also be employed.

While adhesives may be used to attach either or both trim members 50, 64, it is more advantageous to use mechanical fasteners such as screws, nails or staples. For example, the illustrated embodiment has an opening 28 that is fully trimmed and provided with sealing members 48, 72 and a wiper 58 without using any adhesive attachments. This is do both to the mechanical attachment of trim members 50, 64 to wall 26 as well as the integral attachment of seal 72 to trim member 64 and the integral attachment of wiper 58 to trim member 50. When adhesives are used to attach such trim, sealing or wiping members, the adhesive bond is often the location of the initial failure of the trim and seal assembly. Thus, by avoiding the use of such adhesives the illustrated embodiment provides a trim and seal assembly with an enhanced durability.

Furthermore, by having trim members 50, 64 partially overlap within opening 28, the number of trim parts can be kept to a minimum. The efficiency of the installation process is also increased because both trim pieces can be simultaneously secured by using fasteners that extend through the overlapped portion 80 of trim members 50, 64. Although second leg 56 of exterior trim member 50 overlays second leg 70 of interior trim member 64 in the illustrated embodiment, the interior trim member can overlay the exterior trim member in alternative embodiments.

While this invention has been described as having an exemplary design, the present invention may be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles.
